7. Monomicrocaryon euglenivorum fimbricirratum

Foissner, 2016 ( Fig. 7 )

Material examined. Soil sample from Wangsan-ri, Jung-gu, Incheon, South Korea (37°26ʹ47ʺN, 126°23ʹ40ʺ E), on February 2018 .

Diagnosis. Cell size 55-65 × 30-35 μm in protargol preparations, shape ellipsoid; about 19 adoral membranelles; cortical granules lacking; 2 macronuclear nodules, 1 micronucleus between macronuclear nodules; 18 frontal-ventral-transverse cirri, 3 frontal, 1 buccal, 4 frontoventral, 3 postoral ventral, 2 pretransverse ventral, and 5 transverse cirri; 1 left (about 10 cirri) and 1 right (about 9 cirri) marginal cirral row; 5 dorsal kineties; 3 caudal cirri.

Remarks. Monomicrocaryon euglenivorum comprises two subspecies, M. euglenivorum fimbricirratum and M. euglenivorum euglenivorum. Monomicrocaryon euglenivorum fimbricirratum can be distinguished from M. euglenivorum euglenivorum as follows: body length (less than 70 μm vs. 80-90 μm); number of left marginal cirri (less than 11 vs. 15-20); transverse cirri (fringed distally vs. acicular) ( Foissner, 2016).

Deposition. Three slides ( NNIBR2018113 IV1945 - NNIBR2018113 IV1947) have been deposited at the Nakdonggang National Institute of Biological Resources ( NNIBR), Korea .
